S4E2. Students will model the position and motion of the earth in the solar system and will explain the role of relative position and motion in determining sequence of the phases of the moon. a. Explain the day/night cycle of the earth using a model. b. Explain the sequence of the phases of the moon. c. Demonstrate the revolution of the earth around the sun and

the earth’s tilt to explain the seasonal changes. d. Demonstrate the relative size and order from the sun of the

planets in the solar system.

Vocabulary

Keep an eye out for these yellow vocabulary words. They will appear throughout the presentation. Have 7 index cards ready to create your vocabulary flash cards. Try to guess what you think each word means after seeing it in the presentation.

A A satellitesatellite is an object is an object that moves around that moves around another object in space.another object in space.

While Earth revolves While Earth revolves around the sun, it spins around the sun, it spins on an imaginary line on an imaginary line called its called its axisaxis..

The The axisaxis runs from the runs from the North Pole to the South North Pole to the South Pole.Pole.

Earth takes one day (24 Earth takes one day (24 hours) to complete one hours) to complete one rotationrotation on its on its axisaxis..

Day and NightWhat do you think causes day and night?When Earth makes one rotation on its axis (24 hours), day and night occur. The sun lights up the side of Earth that is facing it for daytime and the other side has nighttime.

Seasons

♦ Earth’s axis is slightly tilted.

♦ Seasons are caused by Earth’s tilted axis and the revolution Earth makes around the sun each year.

♦ For part of each year (1/4), the Northern Hemisphere tilts towards the sun and the Southern Hemisphere tilts away. This causes summer in the Northern Hemisphere and winter in the Southern Hemisphere.

Weight on Other Planets

Gravity affects how much you weigh. Gravity is a pulling force. If a planet has more gravity then here on Earth, you will weigh more. If a planet has less, then you will weigh less. This table shows your weight throughout the Solar System if you weigh 100 pounds here on Earth.

Age on Other Planets

A year represents one revolution around the sun. Planets travel at different speeds and some have larger orbits. This would affect your age on different planets. This table shows how old you would be on other planets if you were 10 here on Earth.

Lets go back and review!

Measure the Solar System!Materials: meter stick, adding machine tape (15 meters long), pencil, marker

Directions: In groups of five use the table to create a model of the solar system. Draw a vertical line at the beginning of the tape for the sun. Each measurement given is to be measured from the edge of the sun. Mark you measurements with a pencil. Use the marker to dot and label each planet measured.
